With this data, you can see if there are indexes getting updated too often that can perhaps be removed. This gives you an idea of where the most transient updates happen in the repository. With this information, you can work on reducing the number of excessive writes to Oak.

If Revision GC is slow and you don't find that there is excessive write activity against Oak indexes or other locations in the system, then you can investigate MongoDB performance. Revision GC always runs against the primary MongoDB replica so you could investigate the query times and indexes used in the mongod.log.
